2021 Course Time Cut Offs and Pre-Riding
Time Cutoffs - There are four areas on the course where there will be a time cutoff:
A - Loop 1 - Top of Telluride Trail - 9:15AM
B - Starting Loop 2 - Start/Finish area at Gondola Plaza - 12:30PM
C - Loop 2 - Top of Last Dollar Pass 2:00PM
D - Loop 2 - Vance Junction & Galloping Goose Trail (to go up Illium Rd): 4:15PM
Time cutoffs are in place for rider safety. Sweep riders are sent out at the cutoff time and all course marshals and feed zones will be taken down once the final sweep has passed their position. Riders that do not make the time cutoffs will be scored as DNF (did not finish).
